The Explosion Proof Enclosure and Increased Safety Enclosure Set – IIB + H₂ is a heavy-duty hazardous-area electrical enclosure solution designed to protect critical electrical and electronic equipment in explosive gas and combustible dust environments. Manufactured using stainless steel, light alloy, or galvanized carbon steel, this enclosure set delivers maximum mechanical strength, corrosion resistance, and certified explosion protection for demanding industrial sites.
Facilities specifying a reliable Hazardous Area Enclosure in Jeddah typically install this enclosure system in oil & gas plants, petrochemical complexes, refineries, chemical processing units, offshore platforms, tank farms, and hazardous utility areas. Its modular design allows safe housing of terminals, control components, panels, and instrumentation while complying with strict ATEX and IECEx requirements.
These explosion-proof enclosures are available at Nassguard and supplied across Jeddah, Riyadh, Dammam, Jubail, Al Khobar, and throughout Saudi Arabia.
An explosion proof enclosure (Ex d) is designed to contain internal explosions and prevent flames or hot gases from igniting the surrounding atmosphere. An increased safety enclosure (Ex e), on the other hand, minimizes the risk of sparks, arcs, or excessive temperatures during normal operation.
When combined as a certified enclosure set, these designs offer flexible protection for a wide range of electrical applications in Zone 1-21 and Zone 2-22 hazardous areas, including highly explosive IIB + Hydrogen (H₂) gas groups.
